Abstract

JIS-Stockless Anchor used most often, as described in the preceding paper, was not so much effectual anchor. However, it was expected that the anchor could be got a more efficient holding characteristics provided that the fluke is larger and the tripping palm is more expansive than JIS type. Then we decided to test four model anchors having partly changed forms with above expectation and a few superior anchor, i.e., Danforth patent anchor and Baldt stockless anchor, etc. for comparative study. From the results of these tests, we detected that the holding characteristics can be improved by welding the given plate or palm on the ordinary form, and that the raked tripping palm has effective operation for tripping into bottom when dropping anchor.
